From: "Solra Bizna" To: bug-followup@FreeBSD.org Cc: Subject: Re: kern/121770: [zfs] ZFS on i386, large file or heavy I/O leads to kernel panic or reboot Date: Mon, 17 Mar 2008 02:09:49 -0600 Much hardware and software testing later: The failure occurs under any heavy I/O load, not just ZFS. In addition, it only fails when all three DIMM slots are filled. None of the individual slots or DIMMs are faulty, and the BIOS's memory test passes even with all three slots filled. Currently, the machine is operating with 2 slots filled at a reduced RAM capacity of 1GB. Signs point to a hardware problem, but I want to think it's a fixable software bug because otherwise I'm sitting on a 512MB PC133 DIMM I can't use. :/ -:sigma.SB
